Surface area of a sphere is defined as the total area covered its outer surface. A sphere has surface area equal to 4 π r2 square units. Learn easy and best methods to calculate the surface area of spherical objects at BYJU’S
1. The surface area formula is given by A = 4 (pi) (r^2), where A = surface area and r = radius of the sphere. Hence, using the information given in the question, where r = 2, the formula yields A = 4 (pi) (2^2) = 50.27 cm^2. The surface area of the sph...
The curved surface area of a sphere is the same as the total surface area of the sphere since the sphere is a completely curved shape. Therefore, the formula for the curved surface area of a sphere is CSA of a sphere $= 4\pi r^{2}$, where “r” is the sphere’s radius.Lateral ...
The formula for the surface area of a sphere is V = 4 * pi* r squared, where r is the radius. What is the formula for the volume of a sphere? The formula for the volume of a sphere is V= 4/3*pi* r cubed. In this formula, r is the radius of the sphere. Pi represents ...
The Curved Surface Area of Hemisphere =1/2 × 4 ×πr2 Curved surface area of a hemisphere = 2πr2. Since a sphere is a combination of a curved surface and a flat base, to find the total surface area we need to sum up both the areas. The flat base being a plane circle has an...
A sphere’s surface area is the total area that the surface of the sphere covers, while its volume is the amount of space inside the sphere. Surface area and volume are calculated using different formulas. Why is the formula for the surface area of a sphere A = 4πr²?
Surface area of a sphere formula Given the radius, the total curved surface area of a sphere can be found by using the following formula: S.A. = 4πr2 pi or π is a special mathematical constant, and it is approximately equal to 22/7 or 3.14. ...
Sphere size is calculated using two measures: the volume (how much space the sphere takes up) and the surface area (the total area of the sphere's surface). Both sphere size and surface area can be easily calculated if you know the radius or diameter of the sphere. The formula for volu...
